Missing Steps Poss TB6600 Fault

I actually came to this site on the offchance someone was selling some drivers, failing that I'm online to get something a bit more respectable.

Doddy As you know its hard to beat the AM882 drives

...or to find them in the UK.

Gnngh!, I've spent the last week and then some crafting two folded steel sleds (one power, one control) that fit in the mount-frame of a Starmill... now anything larger than the original drivers isn't going to fit and I'm back to the start, making a tray to take all the gubbins.

Time to go find a cat to kick.

As I have said before you need to up the voltage on the power supply. I would do that first. Those drives you linked to are 50V drives so you should be able to run them at at 40V

Hi, i know what you are saying but i am happy at 24v with the speed and that. it is just the missing steps that i think is being caused either through electrical noise which i will try changing the wiring first. However reading here and on other forum the tb6600 drivers are a common cause of lost steps and failing that is why i am asking about the other drivers as a possible replacement if i have to go down that route.
